Overclocking Amd Fx4100 help
I'm trying to increase my CPU's clock speed. I've managed to raise it from 3.6GHz to 4.0GHz by adjusting the multiplier. Now I aim for around 4.2 to 4.4GHz and need advice on the right voltage. My motherboard has an auto-voltage manager, and CPU-Z shows it's getting 1.312V at full load with Prime95. The maximum temperature I've seen is 39°C, so I'm considering pushing it higher. I have an aftermarket water cooler to keep things stable. Any suggestions would be appreciated, especially regarding the safe voltage range to avoid damaging the chip.
I have an 8350 OC to 4.8ghz running at 65°C with socket temperature under 95 degrees during continuous operation. If cooling isn't sufficient, the CPU will be hotter than with adequate cooling, even if the socket stays at 65°C in both scenarios. To accurately monitor the CPU die temperature, it's better to use AMD Overdrive and check the thermal margin or the throttling point instead of relying on motherboard-reported temperatures.
I've heard that values above 1.5/1.6v can be very risky. You're safe between 1.2-1.3v, you can begin with the default vcore and add .1 ghz. Run a stress test using Prime95 for several hours. If you encounter a BSOD, your CPU might need a bit more VCORE and you should try again. Remember: avoid exceeding 80c during testing. Otherwise, everything should be okay!
Ensure you stay below 80c during stress testing. Exceeding 65c is not advised. For voltage, I haven't tested the 4100 yet—its max limit is 1.5v, starting at 1.3v in factory clocks. I lack sufficient knowledge about it to give specific advice.

"Be careful not to go above 80c during stress tests" pushing past 65c isn't advised.
Regarding voltage, I've never worked with the 4100. For the fx8350, the max voltage is 1.5v area, starting at 1.3v at factory clocks. I don’t have enough info on the 4100 to give specific advice.
But anything above 65c isn't recommended. Let's be honest—do people stay under 65c even when overclocked under P95 load? Above 80c is definitely risky, so it’s best to keep it below that if you can."
ok chips has been working well for a few days now, but i'm facing a whole computer freezing problem. i left it as it is and haven't reached the 40c mark yet, so maybe it can go further, but i don't feel like fixing it right now. just need to resolve this disk issue before it's too late.
I run an 8350 OC to 4.8ghz, using 65C with socket temperature around 65°C all day under prime 95 at 1.5125 volts. Without sufficient cooling, the CPU will be hotter than with better cooling, even if the socket stays at 65°C in both scenarios. To accurately monitor the CPU die temperature, it’s best to use AMD overdrive and check the thermal margin or the throttling point instead of relying on motherboard-reported temperatures.
If you plan to push performance limits, consider using thermal margin settings and aim for values close to 0°C (the start of throttling) without exceeding them. Negative numbers indicate overheating, while 0°C isn’t a safety shutdown temperature but rather a point where the CPU slows to 1.4GHz due to thermal constraints.
65C is still a safe limit; pushing further is unlikely since a socket temperature near 80°C usually signals the VRM is under strain (especially near the socket).
In case you’re curious, my thermal margin setting is 15°C, giving me some flexibility if room temperatures rise or cooling efficiency drops.
